However, on June 27, KIPRIS announced MBK Entertainment's trademark application has been refused. According to KIPRIS, "trademark that consists of the name, title, portrait, signature, seal/stamp, literary name, pen name, stage name, of a prominent person cannot be registered," under the Trademark Act. It's additionally stated that the application can only be approved with the group members' agreement.
